What is the hardest part of working on your own?

I must say that I, luckily, own a lot of discipline and perseverance (thanks to mom). I love to work on my terms and conditions, like deciding my schedule, time to talk with the cat and going out for a good sandwich in my neighbourhood. The only thing I have to watch out for is that, when I’m absorbed in my drawing and inspiration, I sometimes forget to get some fresh air or even to organise a proper meal (my studio is at home so it wouldn’t be the first time I would spend an hour or 72 inside). Luckily work meetings (and also social meetings) are inevitable and help me to not become an enormous nerd completely sunk into his reality
